Round: Test

Round: Technical Interview
Experience: 1. Given an array of size n this contains all integers from 1 to n+1 except one. Array is notsorted. You have to find the missing element by traversing the array only once and no extraspace allowed.(the solution I proposed was to xor all elements of array and all numbers from1 to n+1 the final value of xor is the answer . He asked me to code this).2. Given a string of characters like “34235” convert it to integer format. (I answered like simplesolution. Was told to code it).3. Given a large file. Each line has some string you have to find palindrome in the string andappend the middle element of palindrome to end of string. It was v important to considercase like when you append characters to end of string it may go to next line and create newpalindromes in next line.(I read 1 line from input file found middle letters of all palindromesappended to string and outputted it in new file say output.txt. Now if it has over flown inoutput file handle it in next iteration …).4. Given a program find output c++ program quite tricky. It was using pointers as member ofclass to test allocation and deallocation of memory.
